*************************************************************************
GPDATA Version 3 release Easter 1997 W.B.Langdon for the nested bracket problem
as described in GP-96 $Revision: 1.2 $. 
NB some source code is common with GPkarp
*************************************************************************
Instructions
*************************************************************************

To Make GPbrack:
	Create a symbolic link from brack.h to prob.h
	(eg ln -s brack.h prob.h)

	If gcc is available, make with brack.make 
	Eg make -f brack.make

	If running on an alpha, make with brack.make.alpha

To run GPbrack:
	copy brack.ini to gp.ini and gp.test.brack to gp.test Then run GPbrack

	GPbrack takes optionals command line arguments, these allow the
	user to override the parameter settings in gp.ini Eg

		GPbrack pPopSeed:501

	Evolved solutions can be loaded and their execution traced by
	creating a file gp.load containing the program. eg gp.load.brack

BUGS:
	Sometimes with sparc-sun-solaris2.4 gcc version 2.6.3 fails
	with "Bus error" at end of creating initial population
	Ok with gcc version 2.6.3 on sparc-sun-sunos4.1.3 and 
        DEC C++ V5.3-004 on Digital UNIX (Alpha)

	A number of bugs have been fixed since the bracket problem was
	first solved. However the code in this kit reproduces the
	reported behaviour in GP-96. Symbols defined in
	brack.h (eg ORIGINAL_DEME) are used in some source
	files to disable some bug fixes. You may like to revise the
	sources, eg to use new symbols. 

	Behavour is not _identical_ to earlier version but nontheless
	solutions to the bracket problem are evolved
